修改指向仓库的 Docker 映像链接

积累知识，胜过积蓄金银！毕竟在Golang开发的过程中，会遇到各种各样的问题，往往都是一些细节知识点还没有掌握好而导致的，因此基础知识点的积累是很重要的。下面本文《修改指向仓库的 Docker 映像链接》，就带大家讲解一下知识点，若是你对本文感兴趣，或者是想搞懂其中某个知识点，就请你继续往下看吧~

我在更改项目和建筑时遇到问题。

https://github.com/schollz/find3

我尝试克隆 docker 映像并对文件进行了一些更改，并从中创建了新映像，但映像中没有反映任何更改。

后来我从 dockerfile 中发现，这个项目正在克隆在线 git 存储库并从头开始重新构建。

如何更改此项目并在 docker 中构建它？

# docker build -t find3 .
# mkdir /tmp/find3
# docker run -p 11883:1883 -p 8003:8003 -v /tmp/find3:/data -t find3

正确答案

您可以分叉存储库并将此行更改为指向您分叉的存储库：

git clone https://github.com/schollz/find3 && \
